IMPROVEMENT IN LAMPS Specification forming part of Letters Patent No.37,068, dated December 2, 1862.

To all whom it may concern:

Be it known that I, EDWARD O. BLAKES- LEE, of \Vaterbury, in the countyof New Haven and State of Connecticut,haveinvented, made, and applied touse a certain new and useful Improvement in Lamps; and I do herebydeclare the following to be a full, clear, and exact description of thesaid invention, refereuce being had to the annexed drawings, making partof this specification, wherein- Figure l is a vertical section of mysaid improvement, and Fig. 2 is a plan of the same.

Similar marks of reference denote the same parts.

The nature of my said invention consists in abent lever having itsfulcrum on the cap that carries the glass chimney, and acted upon by aspring in such a manner that the chimney is retained within its ring orsupport by means of said bent lever, or can be easily lib erated fromthe same by pressing back this spring-lever.

In the drawings, a is the cap, that is screwed upon any suitablereservoir containing the liquid to be burned. This cap rises in theusual manner to the ring I), for the glass chimney c, and d is theordinary deflector, with an opening over the wick-tube 0. These parts,being of any known construction, do not require further explanation.

g is my bent lever, passing through a mortise in a, at which pointitforms a fulcrum. 1, for said lever. The upper end of my bent lever is ofa shape adapted to take over the flange of the glass chimney c, and theend forms a thumb-piece, so that the lever can be moved to liberate thechimney when required.

In order to keep my bent lever to the chimney, Iemploy a spring actingat the inner end of said lever. I have shown the spring h as attached tothe wicktube e and cap a, and acting upon the short inner arm of my saidbent lever 9, but it will be apparent that this spring may be made as apart of theinner end of this lever, as shown in the detached view, Fig.3, or otherwise applied so as to press the lever to the glass chimney.This means for holding on the chimneyis strong and durable. At the sametime it will yield as the chimney expands under the action of the heatof the flame, and not break the glass, as often occurs where a screw isemployed.

6 6 are cars on the ring I), to hold the chimney on the opposite side tothe spring-lever 9.

What I claim, and desire to secure by Letters Patent, is

The bent lever g on the fulcrum l and actuated by a spring, as setforth, in combination with the flanged chimney c and ring or holder 1),for the purposes and as specified.

In witness whereof I have hereunto set my signature this 7th day ofJuly, 1862.

EDWARD C. BLAKESLEE.
